Who can tell me index numbers for the following very good rule: early surrender, including after double, but lose all to a BJ.
I think never double against a dealers ace, right?
Double 11 against a ten is basic strategy there, but index number? I am interested in several systems, especially in the systems 11111000-1-1 and 1223221-1-30, each with a side count of aces. Does anyone know index numbers, maybe even including the side count of aces?
Double against 7, 8, 9 is no problem because the no-hole-card rule has no influence. But when to surrender after double? Basic strategy says against 8, 9 if you are below 17. But the propability of dealer to bust will go down in high counts, when should I surrender 16 or less against a 7 (I cannot take a card because I have doubled)?
Is there a low count at which you should stand against 8 or 9 with 16 or less, i.e. at that the propability of dealer to bust is more than 25%?
Thanks in advance
